HARVESTER-RAKE.

SPECIFICATION forming part of Letters atent No. 278,979, dated June 5, 1883.

Application filed November 20, 188:2.

.To all wiz/om, it may concern,

Beit known that I, CHRisTorHEn LrnnEN, of Lafayette, in the State of Indiana, have invented certain new and useful Improvements in Harvester-Rakes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of `reference marked thereon, which form part of and S are sectional details of the rake which moves the loose grain toa binding apparatus.

My invention relates to rakes for moving the loose grain across the platform to a grainbinding mechanism, and then discharging the sheaves from the machine.

My invention consists, in general terms, of a rake and rakeoperating mechanism, whereby, as the rake sweeps the grain -platform and carries the grain forward to be bound, the rake shall move in a straight course over the platform with its teeth upright, and as soon as it has delivered the gavel to a compressor it shall move backward and swing around to its iirst position with its teeth dropped, thereby returning above the platform after it has delivered the gavel. Also, to a rake which is reciprocated automatically at right angles to the sheaf-rake, and which operates in harmony with it for removing the sheaves from the binding mechanism and discharging them from the The following particular description7 when taken in connection with the annexed drawings, will enable others skilled in the art to fully understand the same.

By reference to the annexed drawings it will be seen that I have represented in connection with my raking devices a compressing and binding apparatus. This. I shall describe in general terms, and refer to it only in so far as (Model.)

son that said apparatus forms the subject of my application for Letters Patent filed lSepv tember 26, 1882, and is not herein claimed.

The various parts ofthe main frame are indicated by the letter A, and are constructed and arranged so as to constitute suitable supports for the various operative devices which will now be described. Y

B designates the finger-bar, which is movable forward and back below the front platform, A. A2 designates a secondary platform, which extends partly over the platform A, leaving a space for the operation of the gavel-rake. The movable'finger-bar is not claimed in this application, as it is fully described and claimed in Amy application above referred to.

C designates the rake which is employed for sweeping the platform and moving the grain forward to a compressing-arm, D, and' a cordcfarryin g binding-arm, G, which have their fulcra on a post, d, located at the inner end of the platform A and front end of the platform 4 t. The rake-teeth C are pivoted to one of a pair of parallel flanges, or to one of the'walls of4 a longitudinal channel which is formed at the outer end of a sliding bar, C?. The buttends of the rake-teeth C are pivotally connected to a second and somewhat smaller slide-bar, C, which works in the said channel in the slide-bar C?, and also through guides c c, formed with or attached to said bar. The slide-bar C2 works in suitable guides, c, on an oscillating bar, 0*, which is provided at its rear end with a slot, c, and pivoted to the main frame by means of a pivot, c,- which passes through said slot and is secured to the rear bar of the said main frame A. Thisanode of connection admits of a limited longitudinal play on the part of the bar 0*, as well 4as an oscillatory or swinging movement thereof. lTo the said oscillatory ba-r C* is pivoted a bellcrank lever, 0*,the longest arm of which is connected to the small slide-bar C? by means of a connectii'ig-rod, C". vof the bell-crank lever c* is connected to a crank-arm, Cf", by means of a connecting-rod, C7, said crank-arm being xed uponv the axle4 10o The remaining arm ing and'driving wheels of the harvester, and constitutes the source from which power is derived for driving and operating the several devices herein shown.

C" indicates a stationary curved guide, which is secured to the main frame A below the oscillating bar L, and c" denotes a pair of antifriction rollers carried by a plate, c, which is pivoted to the under side of said oscillating bar. These rollers 0' embrace the sides of the curved guide-bar C", so that as the bar C* is swung about its pivot it will be alternately rctreated and advanced to an extent which is limited b v the length of its slot c".

ci designates a pair of dogs or stops, which are pivoted to the rear edge of the grain-platform A, and adapted to be engaged at certain periods of the rake movements by a projection, c, upon the slide-bar C2, for the purpose of facilitating the rise and fall ofthe raketceth C. After the gavel -rakc has been swung away from the binding-arms D G and carried to the grain side ofthe machine, the slidebar cwill be in a retracted position upon the bar (t, and the slide-bar C will be retracted upon the bar C2 with the rake-teeth lowered. As the bell-crank lever upon theoscillat-ing bar C* is caused to vibrate by reason of the rod C pulling upon its short arm, the connecting-rod Cf', pivoted to the remaining` arm of the bell-crank lever,'will first throw the slidebar C forward so as to raise the rake-teeth C. A lug, b5, on the slide-bar (li, to which the forward end of conncctingrod (f5 is pivoted,

strikes a projection, n, on the slide-bar CP' during the forward movement of the slide-bar, which is connected to the lower ends of the teeth, and throws the slide -bar C forward, thus bringing the rake into position for carrying the gavel over the platform A. After the rake has traversed the platform the connecting-rod (l5 willretract the bar C, causing the teeth C to drop and the lug bf on said'bar to abut against the inner guide, c, on slidebar C1, thereby retracting said bar, and also causing the said bars and the rake to be swung back to the first position. slot c2 in the oscillating bar Ct, and the curved guide C", against which its rollers bear, the forward end of said bar will during its oscillating movements traverse the platform in substantially a straight line, instead of in the arc of a circle, thereby keeping the rake projected forward to the same extent during the process of carrying the gavel up to the compressing and binding arms. Vhen the bar CL is extended its stop es will strike one of the pivoted dogs cT and ride over the same,`where by the raising of the rake-teeth to anvupright position will be insured. After the gavel has been delivered, and while the slide-bar C2 is being retracted, its said stop will strike the remaining pivoted dog, which will insure the rake -teeth being completely thrown down. As thus arranged, it will be seen that by reason of the bell-crank and the two connectingrods the slide-bar C3 is actuated so as to raise reason of the the rake-teeth C preparatory to sweeping the platform, and to lower the teeth after the gavel has been brought by the rake into position to-be acted on by the compressing-and binding arms. The extension or slide bar Cf" is thrown and held forward while the rake is sweeping the platform and retracted after the gavel has been brought up to said compressing and binding arms, and the oscillatory bar carrying the rake extension bar is caused to swing about its pivot.

T indicates the rake for carrying off the sheaves. This rake is pivoted to a slide, T, which reciprocatcs on an elevated horizontal guide-bar, f, supported above the way or platform t7, which is a rear extension of the platform A. The slide T/, carryingtherakc T, is connected to a lever, T2, by means of a connecting-rod, TX, so that as the said lever is vibrated the slide and rake will be moved back and forth. to the main frame, and is actuated by a connecting-rod, T, which connects the said lever T? to a crank-arm upon thc axle ofthe sprocketwheel C"`. The rod T has a slotted connection with the lever T2, so that this rod shall haveV a certain extent of motion before actuating lever T1. A two-armed dog, T, is pivoted to the rake-slide, and two stops, t", are located on the bar 1, or upon this bar and one of its supports, in the path of the lower arm of the dog T. Vhen the slide T is drawn back, the lower arm ofthe dog strikes the rear stop, ff, whereby the dog will be turned so that its upper arm will raise and hold up the rake. Then the said slide is moved forward and the rake brought over the bound gavel, the lower arm ofthe dog will strike the tbrwardstop, ti, and thereby canse the dog to turn so as to trip the rake and allow it to engage with the gavel.

Having described my invention what I.; claim as new, and desire to secure by Letters Patent, is-

l. In combination with a horizontally-vibrating rake-arm having vertically-vibrating The lever Tf" is pivoted at one end IOO IIO
